Just after Apple released iOS 17 RC to developers and beta users last week, I found links to code for a new option that allows you to limit the maximum battery charge on your iPhone in order to preserve it better. Since some people already have the iPhone 15 in their hands, we now have confirmation that this feature exists on the new phones. In addition, they provide users with more detailed information about the battery status.
Features of the new iPhone 15 battery
How shared Ray Wong on XiPhone 15 models have a section dedicated to more detailed battery health information. For example, users can check when a component was manufactured and when it was first used. There are also details on cycle counting (a cycle is counted every time the battery is recharged from 0 to 100%).
This information was already available on previous iPhone models. However, this required the use of some third-party tools such as CocoBattery on Mac. This information is now available as part of iOS, at least for the iPhone 15.
The iPhone 15 has another new battery feature: the ability to limit the charge to 80%.
first introduced this option last week, and now we know for sure that it is already available for those who buy the iPhone 15. Since charging a lithium-ion battery to 100% causes it to age faster, users may be sacrificing a few extra hours. daily battery life to ensure the component lasts longer.
This feature works similar to Optimized Battery Charging, which learns the user’s daily routine and finishes charging the battery above 80% around the time the user unplugs the iPhone from the charger. However, the new option will always limit the cooldown to 80%.
And older iPhones may not receive them.
Unfortunately, both new features are limited to the iPhone 15 models for some reason. It’s unclear at this point whether Apple plans to add the same features to previous iPhone models with a future software update.
iPhone 15 goes on sale this Friday, September 22. Apple says the new phones will go on sale in 20 more countries next week.
